HENRY W. OSTROM, OF GRAND RAPIDS, MICHIGAN.

Letters Patent No. 103,918, dated June 7, 1870.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it'may concern Be it known that I, HENRY W. OSTROM, of GrandRapids, in the county of Kent and State of Michigan, have invented anew' and useful Improvement in Cultivators and Gang-Blows; and I dohereby declare the following to be a full and correct description of thesame, suflicient to enable others skilled in the class to which myinvention appcrtains to understand the same, reference being had to theaccompanying drawings which make part of this specification, and inwhich- Figure 1 is a rear elevation of my improved cultivator, and

Figure 2 is a plan view of the same.

The nature of my invention-consists in the arrangement of an independentcross-bar, Which' may be adjusted higher or lower to prevent thesections from being thrown up violently by the unevenness of the ground,and to afford a bearing for the section beams when operating; also, inthe arrangement of the varions parts of the cultivator.

A A in the drawings represent a strong square frame, through the sidesof which passes an iron rod or bar, N, to which the several sections BB, B B B, and B B of plow-bars are pivoted. These bars carry at theirfree ends cultivator-teeth or plows H, and each section of bars isconnected'bymeans ofchains I to its levers E E E, respectively, whichlevers are pivoted to the axle-tree M, 'in any suitable manner, theirfree ends converging toward each other, and held, when desired, bycatches G, secured upon the tongue K.

Upon the rear of cross-bars D of frame A are secured supports orstandards 0, which passthrough a cross-bar, 0, situated across the endsof bars B. This cross-bar O can be adjusted higher or lower on thestandards 0.

' I are chains attached to the frame A for the purtor or as a gang-plow.

pose of raisingor lowering the same, catches on the axle-tree holdingthe chains.

The bars B B B are alternately shorter and longer,

as shown.

Rods F hold the front end of the frame A to the axle. 1

By arranging the plow-bars in sections which can' be elevated orloweredjndependently from each other, I am enabled to use my machineeither as a cultiva- When used as a cultivator, the levers E are removedfrom under the catches G, which allows the three sections ofcultivator-teeth to drop on the ground, the bar 0 being adjusted to theproper and desired height on standards 0. When used as a gang-plow, twosections are elevated by placing their levers under their catches G, andleaving one of the sections down, changing the cultivatorteeth tosuitable plowshares. Either of the sections be used as a gang-plow,according to the ground to be gone over.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is

1. Theindependent cross-beam. 0, arranged adjust ably on the standards0, substantially as and for the purposes set forth.

2. The combination of the sections of plow-beams B B B levers E E Echains 1, catches G, on tongue K, standards 0, cross-beam O, and chainsI, all arranged in frame A, to operate as herein described and shown.

Signed at Hamilton, Ontario, Canada, on thelfith day of August, A. D.1869, in presence of- HENRY W. OSTROM.
